12 Claims.

The presentV invention relates to an improvedY adjuster for operating Casement windows and the like.

Heretofore, various types of adjusters have been devised wherein they are capable of swinging the window sash to an open posi-tion solely by a right or left movement as the case maybe. Other types have' been advocated wherein are-arrangement of the operating parts is necessary to accommodate the swinging in the required direction. In all of said types, the friction which exists between the moving partsl has noticeably retarded the easy operation of the sash, and the sagg-ing of the sash and strain upon the various parts hasrtended to place the assembled parts out of plumb and also to impedel and detract from 'the proper functioning of the various parts. Then too, the slots` occurring" in f the' adjuster usually extend completely thru it thus making the de- 26; vice unsightly, and tending to cause it to become inoperativebyv reason of dustl and foreign particles collecting in theslotted portion thereof. Furthermore additional stock has for this reason been required in order to providey adequate strength.

The aims and objects of the presentV invention are to eliminate these several disadvantages which collectively tend to retard the sales of such devices inthe market.

A summary of the objects is: First, to provide in a device of the above character an adjusting arm having acam groove of an endlesscharacter in its underside, to cooperate with' a pin adaptedto travel in the groove for the purpose of renderi ing the arm usable with either a right or left hand swinging sash.

Second, to provide awearing strip on the upper face of the adjusting arm tov engage with asupporting flange of a bracket which is fastened to x the'sash and said supporting bracket'having a pin which projects upwardly to engage with the cam groove aforestated.

Third, to provide an adjusting arm having a cam slot on the underside which may be kept in 5i a lubricated condition and free from dirt andV silt'l In the drawing: Fig. l isy a' perspective view showing theU invention applied to' a Casement sash which is shown in its partly opened position.

Referring in detail to the drawing, the invention isrshewn applied to awindow sash I fastened 5" by meansof a butt 2ito'a windowstile 3.

The window screen 4A swings inwardly and the sash I? `swings outwardly, that'is to say, away from the observer, as viewed in Figi. 1f. The hinge mounting forthe screen is not shown, but it is 10 preferably located at the same side of the window opening asv are the hinges for the sash.

The mechanism 5 for operating the sash is mountedupon the sill 6 between the sash and the screen and is* designed in such a manner as' 15' to accommodate itself to the minimum distance existingbetween thesash and the screen at present pr'ovidedby thebuild-ing trade. Said mechanisrn is operated by means ofA a crank 'I having ashaftr or shank portion Ia which is extended 20 thru an opening in the sash of the screen. An escutcheon 8v is secured to the sash of the screen, said escutcheon having thru it an opening I0' which alines with the-opening thru the sash of the screen. The" greater portion of the wire part of 25 the screen isbroken away in Fig. 1- in order to aveidVobscuring the sash operating mechanism.

The sash operating mechanism 5 includes a base plate II, a cover plate I2, a swingable operating arm I3 journalled between said plates and a 30 worm: I4 uto move said arm, in combination with a bracket I5 which is attached to the sash. Said pla-tesy Hand I2 Vmay be designed otherwise than illustrated in the drawings, to suit the taste of the manufacturer, the essential thing being that they cooperate to furnish a secure and satisfactorymounting means for the movable parts of thef operating mechanism.

shown in Figs. 1 and 2 of the drawing, the base plat'e-v I Iv is; at its'leftV-end provided with an apertured; extension IIato* receive an attaching screw I6i At itsother end it underliesthe cover plate; the'sel-p1ates" having alining apertures to receive screws II whereby said.` plates are secured to each other' as well as'to' the-sill.

BetweenY the holes'- fori the 1 screwsL I'I the plates II and I2 are each provided' with an yape'rtii're intowhich iscl'oselyY ttedafdoweli-pin I2'd.-V In Fig". 2 the aperture IIdin theb'ase plate II" is" show-'ri into' which the lower` en'd oi"- the dowel'pin? 5 snugly fits; This dwelf pinlha's'i-be'en foundinpracticelgtob'e very'necessari7 asia meansffor' prop`' e'r-ly positioning the plates' inf order that* the wormi ldmaybe maintained'in a proper operative relation to the other moving-parts;

The juxtaposed faces of the base plate and cover plate are recessed to house the Worm I4 and to provide bearings for its end portions or hubs I8 and I9. I'he hub I8 is provided axially with a square socket with which a square end portion of the crank cooperates.

The base plate is constructed with an extension 22 and the cover plate with an extension 23. Between said extensions is mounted a segmental gear 24 formed integral with the sash operating arm I3. In the arrangement shown in the drawing, said gear 24 meshes with the worm I4 to swing said arm outwardly when the crank is operated in a clockwise direction, and to swing said arm inwardly when said crank is operated in a counterclockwise direction, but, as Will be explained later, the location of the operating mechanism may be reversed with relation to the window opening in order to operate a sash hinged to the opposite side of the window opening.

The gear 24 is held in mesh with the worm by means of a cap screw 25 which is tapped into the extension 22. The operating arm is thus pivoted to swing about the screw as an axis. The two faces of the gear are flat and operate between the extensions with a working t to cause the arm to remain in the same plane during its swinging movements. This arrangement offsets the tendency of the window to sag.

In its under face the arm I3 is provided with a double groove of a continuous character having the two runs or tracks, 26 and 21 which are separated from each other by the rib 28. There is a clearance 29 at one end of this rib to provide a connection between the two runs of the groove. At the opposite end oi the rib there is pivotally mounted a pointed switch arm 39, the function of which will presently appear. Beyond said switch arm the two runs of the groove are merged into a short groove extension 3I which alines with the rib 28.

The bracket I5 carried by the sash I comprises a base supporting flange or arm I5a and a side attaching flange I5b which extends at a right angle to said base ange. The attaching flange I5b receives screws 32 whereby the bracket is attached to the sash. As a convenience in assembling the parts, said flange I5a is shown attached to the body portion of the bracket by means of a pair of screws I5c one of which is shown in Fig. 5. In a vertically spaced relation to the base flange I5a the bracket is provided with an upper flange or arm 34 to support the sash if it tends to sag.

Directed upwardly from the mid-width of said base flange is a cylindrical shank 33 which, with a working fit, operates in one or the other of the groove runs 26 and 21 to open and close the sash. Said shank 33 may be the stem of a rivet-shaped bolt which is driven friction tight thru an aperture provided therefor in the base ange I5a.

Along the mid-width of the upper face of the operating arm I3 there is preferably a wearing strip 35 to engage with the flange 34 of the bracket to minimize the friction between these parts and to protect the body portion of the arm from an unsightly wearing away.

As illustrated in Fig. 4 the switch member 3D is constructed and arranged in such a manner that, when swung completely to either side it forms a continuation of the adjacent wall of the opposite run of the double groove along which the shank 33 travels, thus directing said shank into the groove extension 3I when the closing movement of the window is completed.

In assembling the parts, the flange 34 of the bracket I5 is disposed transversely to and caused to engage the upper side of the swingable arm I3 and then after the shank 33 has been brought into proper operative relation to the desired run of the double groove the bracket arm I5a is secured to the body portion of the bracket by means of the screw I5c.

When the device is mounted in the relation to the Window opening shown in Fig. 1, the run 2 of the slot will be traversed in reverse directions by the shank 33 during the opening and closing movements of the window, and the switch member 3D will at all times occupy the full line position of Fig. 4, thus forming a continuous track between the slot run 2'! and the slot extension 3I. When the device is placed at the other side of the window, the switch member will continuously occupy the dotted line position of Fig. 4 thus conducting the shank 33 from the groove run 2B to the groove extension 3l, and vice versa. The pivotal mounting of the switch member 30 should be suiciently snug to guard against accidental displacement of the switch while the shank occupies the slot extension 3 I, as is the case when the window is fully open.
